Leukomalacia with ruptured saccular aneurysm.

A 42-year-old woman with a ruptured saccular aneurysm of the internal carotid artery developed large areas of cerebral leukomalacia, resulting in hemiparesis and an obtunded mental state. A significant factor in the development of the white matter lesions was episodic hypotension, leading to reduced cerebral blood flow in a patient whose cerebral circulation was already compromised by vasospasm secondary to the subarachnoid hemorrhage. This case illustrates yet another clinical situation associated with the development of white matter necrosis.

An epidemiological study of rheumatic fever and rheumatic heart disease in Lagos.

In Lagos 12 755 schoolchildren aged between six and 12 years were screened for evidence of rheumatic heart disease and showed a prevalence rate of 0.03%. Group C (27.7%) and group G (47.3%) predominated in the throat and in cases of pharyngitis, while group A predominated on the skin. Two hundred and sixty-six cases of pharyngitis were recorded, 70 (26.4%) were positive for beta-haemolytic streptococci. Half of the cases of streptococci while 28.2% and 21.1% were caused by groups C and G respectively. A diversity of serotypes of group A streptococci, which included types 49 and 55, and C and G streptococci were isolated from impetiginous skin lesions. The main point of interest is the association of group C and G streptococci with sore throat and skin infections. The pathogenicity of C and G in such circumstances merits further investigation. The present study also showed that prophylactic benzathine penicillin (Penadur) given to patients with rheumatic heart disease or rheumatic fever had been effective with no recurrent attack of acute rheumatic fever.

Obscure stenosing aortitis and arteritis associated with perivascular lymphadenitis--combined angiographic and lymphographic evaluation.

A series of eleven cases of an obscure occlusive type of aortitis and arteritis is reported. These are characterised by chronic nonspecific perivascular lymphadenitis and fibrosis, constricting the lumen of the vessels. Subsequent spread of the inflammatory process produces irreversible changes in the vessel wall. Timely excision of the nodes, release of fibrous strands and decompression of the vessels may result in a permanent cure; The inflammatory process is nonspecific in nature. The etiology is obscure and is subject to speculation. Tuberculous inflammation of the lymph nodes appears to be unlikely while filarial lymphadenitis is probable. The disease is not a primary panarteritis as observed in Takayusu's disease or allergic vasculitis. Males are predominantly affected and present invariably with clinical signs and symptoms of peripheral vascular obliterative disease of the lower extremities.
